If you read the thorough white paper written by @wynpalmer4 , one would not be surprised that this phono stage sounds excellent and competes with much higher priced phono stages.
How do I know? One of my phono stages uses opamps and it is fantastic. Competes with the many discrete and tube units I have owned over the years. The good designers of today will tell you that opamps have improved greatly over the years and I believe they are right. I would like to try this phono stage.
